It has for its object to provide a device having the means for securing them to the fabhaving a number. of improved features over ric at the end of the member, or in line with. the devices now in use. One of its main objects the axis of the member, have the securing means is to provide a device in which the members on one side, as plainly shown at IS in Fig. 11. 3 secured together are placed parallel, or at an These securing means consist preferably of a angle, to one another instead of on the same substantial circular opening ll into which a plane as is now the case. Another object is to slot i8 opens. so construct the device that the customary "slide?

it is possible to move the slide downward by Pulling on the fabrics in the directions indicated by the arrows 3|. This is objectionable, particularly where the slide operated fasteners are used on any articles exposed to the wind, as it often causes the unintentional opening of the fasteners. To overcome this, inwardly extendin books 32 are provided on the sides 33 of the slide. These hooks are plainly illustrated in Fig. 4. It is evident that any movement of the fabrics in the direction of the arrows will cause the interlocking members of the fabrics to engage against these hooks and thus prevent the slide from moving.

The embodiments shown in Figs. 1, 2, 4 and 10 illustrate the use ,of the device, as for example employed upon a satchel or similar article in which it is advantageous to place the fabric members parallel to each other, as in Fig. 4. In

such cases the finger grip 23, when employed, is placed on the front face of the slide. There are many cases, however, where it may be required that the fabrics extend sidewardly as shown in Figs. 3, 6 and 7. In such cases, an arm 34 is extended downwardly from the member 25 and on this arm the rail A, on which the finger grip 23A is mounted, is formed. Thus when the fabrics i and II are bent sidewardly, m shown, the fastening device as well as the slide proper, are on the rear of the material, only a very small portion of the fasteners being shown. The arm 34 and the finger grip 23A are the only parts of the slide shown on the outer or front part of the fabrics.

This feature is particularly advantageous in cases where it is desired to make the device as inconspicuous as possible. It has also another great advantage, in that, in this construction, the slide may be operated from both sides of the fabric, as for example if used on a tent flap. In such cases, when the slide is operated both from the inside and the outside of the tent, it is advantageous to place a finger grip both on the slide proper and on the arm 34, as in Fig. 5. The ordinary stops 35 and 36 are used at each end of the device. .The stop 35 secures the fabrics together and prevents downward displacement of the slide and the upper stops 36, by being aligned with each other, prevent upward displacement of the slide.

From the foregoing it will be seen that the 'present invention has many advantages over the fasteners now on the market. Principally among these may be mentioned that the interlocking members may be placed directly on the articles without an interveining tape, as is now the case and with the materials of the article parallel to each other. The slide may be locked in any position and operating from either one side or the other. Accidental opening of the fastener 'is prevented and less of the fastening deviceitself is exposed to view.

Having described the invention and its objects,

what I claim as new and wish to protect by Letters Patent is:

1. A slide, for slide-operated fasteners, having a member extending over the top of the slide and adapted to pass between the interlocking members of the fastener as the slide is moved 1 and which, when turned transversely to the interlocking members of the fastener, will engage with one of these interlocking members and prevent the opening of the fastener; and a finger grip secured to the front face of the slide for operating same.

2. A slide, for slide-operated fasteners, having a member extending over the top of and down over the rear face of the slide with the top of the member adapted to pass between the interlocking members of the fastener as the slide is moved in one direction or the other; a bearing formed on the top part of said member; a shaft rotatingly mounted in said bearing axially with the slide; a handle member secured to the upper end of said shaft; a detent secured to the lower end of the shaft and which, when turned transversely to the interlocking members of the fastener, will engage with one of these interlocking members and prevent the opening of the fastener; a finger grip secured to the front face of the slide for operating same; and another finger grip slidingly mounted on the downwardlyextending member on the rear face.

3. A slide, for slide operated fasteners, of the class described; a bearing formed in the top thereof; a shaft rotatingly mounted in said bearing axially with the slide; a handle member secured to the upper end of said shaft; a detent secured to the lower end of the shaft and which, when turned transversely to the interlocking members of the fastener, will engage with one of these interlocking members and prevent the opening of the fastener, and a finger grip secured to the front face of the slide for operating the same.

4. In a slide for slide-operated fasteners of the class described; a bearing formed in the top thereof; a shaft mounted in said bearing axially with the slide; a detent secured to the lower end of said shaft; a handle member secured to the upper end of said shaft for interposing said detent into engagement with one of said interlocking members to prevent the opening of the fastener; and a finger grip secured to the front face of the slide for operating the same. a

5. In a slide for slide operated fasteners of the class described; a bearing formed in the top thereof; a shaft mounted in said bearing axially with the slide and having a detent secured to the lower end thereof for interposition between,"

and engagement with, the interlocking members to prevent movement of the slide; means for interposing said detent into locking engagement with the fastener members; and a finger grip secured to' the slide for operating the same.

6. A slide for slide operated fasteners comprising a flat piece of stamping metal having its edges turned to form opposite guide and wedging elements, one face of the slide having an extension which is turned over the top of the slide and down over the opposite face of the -a longitudinal slot on said face, and a second finger grip mountedv for sliding in said slot.
